摘要：

研究了利用新型多元微电解联合催化氧化技术处理高浓度制药废水。在制药废水pH=3.5时，随着微电解处理停留时间的延长，其COD去除率不断上升，最高可达60%。催化氧化过程中使用双氧水为氧化剂，最佳添加量和反应pH分别为0.2%、3.0。为保证微电解稳定高效，进行了两级微电解+催化氧化处理制药废水的中试研究。结果表明，两级微电解耦合催化氧化处理制药废水中试COD去除效果稳定，微电解停留3 h时，最高去除率可达68.5%。

Abstract:

The application of a new type of diversified micro-electrolysis combined with catalytic oxidation process to the treatment of highly concentrated pharmaceutical wastewater has been studied. When the wastewater pH is 3.5, the COD removing rate increases continuously with the extension of staying time of micro-electrolysis(ME). The re-moving rate can be as high as 60%. In the process of catalytic oxidation,hydrogen peroxide is used as the oxidant, and the optimal dosage is 0.2% and pH is 3.0. Furthermore,to ensure that ME is stable and highly efficient,a research on a' two-step ME+catalytic oxidation' pilot test has been carried out. The final results show that the COD treatment effect of this process is stable. When the staying time of ME is 3 h,the highest removing rate can reach 68.5%.
